The chassis 1 is provided with a traveling mechanism 1-1, and the traveling mechanism 1-1 can automatically advance to further drive the whole self-moving tail to move, so that the self-moving tail can freely move in a large range. In the embodiment, the travelling mechanism 1-1 specifically comprises a crawler-type travelling mechanism, so that the travelling stability is high; in other embodiments, the belt conveyor self-moving tail can also be a wheel type travelling mechanism, and the longitudinal X forward movement of the belt conveyor self-moving tail is realized through the rolling of wheels. Specifically, the traveling mechanism 1-1 may move forward or stop upon receiving a signal from the controller.
At least part of the structure of the material receiving platform 2 is arranged above the chassis 1. Specifically, the material receiving platform 2 comprises a material receiving main body, and the material receiving main body is supported by the chassis 1. More specifically, the material receiving main body comprises a platform main body 2-3 and a material receiving device 2-2 arranged above the platform main body 2-3, the platform main body and the material receiving device 2-2 are fixed together, and at least part of the structure of the platform main body 2-3 and the material receiving device 2-2 are positioned above the chassis 1. The material receiving platform 2 is directly supported by the chassis 1, and in addition, the traveling mechanism 1-1 can drive the material receiving platform 2 to integrally move along the longitudinal direction X.
Two ends of the first telescopic driving device 3-1 are respectively hinged to the material receiving platform 2 and the chassis 1 and are specifically connected between the platform main body 2-3 on the material receiving main body and the chassis 1. Through the extension and retraction of the first extension and retraction driving device 3-1, the transverse Y position and the angle of the material receiving platform 2 can be adjusted, and the material receiving platform 2 can swing relative to the longitudinal X on the chassis 1. In this embodiment, the transverse direction Y, the longitudinal direction X, and the up-down direction are perpendicular to each other. When the length of the first telescopic driving device 3-1 is kept unchanged, the relative position relation between the material receiving platform 2 and the chassis 1 is determined, and the material receiving platform is in a rigid connection state.
When the equipment runs, the traveling mechanism 1-1 is started, the chassis 1 drives the material receiving platform 2 thereon to synchronously move forwards along the longitudinal direction X, corresponding to the right direction in fig. 1, when the traveling direction of the traveling mechanism 1-1 is found to deviate from the original route, can synchronously drive the material receiving platform 2 to deflect or transversely move Y relative to the original route, because the return of the travelling mechanism 1-1 requires the travelling mechanism 1-1 to travel a certain distance again, in order to ensure the material receiving effect of the certain distance, the material receiving platform 2 can be adjusted back to the original route by the extension and retraction of the first extension and retraction driving device 3-1, the material scattering is reduced, the advancing direction of the travelling mechanism 1-1 is adjusted, and the extension and retraction of the first extension and retraction driving device 3-1 can be adjusted adaptively while the advancing direction of the travelling mechanism 1-1 is adjusted, so that the transverse Y position of the material receiving platform 2 is kept.

Wherein, part of the third telescopic driving devices 3-3 are telescopic oil cylinders, and the rest are sensor oil cylinders to control the stroke.
When the material receiving platform moves forwards, the chassis 1 drives the material receiving platform 2 to move forwards, the extension device 4 is connected with the material receiving platform 2 through the third telescopic driving device 3-3 and moves along with the material receiving platform 2, and the third telescopic driving device 3-3 can adjust the relative position of the extension device 4 and the material receiving platform 2 in a telescopic mode. When the belt feeder moves forward from the tail of the belt feeder, the conveying distance is lengthened, the extension device 4 provides a space for installing the frame, the belt is supported all the time, smooth non-stop operation of the belt feeder is guaranteed, and the effect of prolonging the conveying distance can be achieved.
The theory of operation of belt feeder self-moving tail that this embodiment provided:

When the situation occurs, the deviation adjusting device 3 starts to act, and when the deviation of the belt conveyor caused by the self-moving tail of the belt conveyor is detected, the first telescopic driving device 3-1 and the third telescopic driving device 3-3 act simultaneously to adjust the relative positions of the material receiving device 2-2 and the center of the belt conveyor, so that the effect of initially adjusting the actual moving route of the whole self-moving tail is achieved; in the moving process, the tail roller 2-1 may deviate to cause deviation of the belt conveyor, and the relative position of the tail frame 2-4 and the material receiving device 2-2 is changed by adjusting the second telescopic driving devices 3-2 positioned at two sides of the tail frame 2-4, so that deviation adjustment of the tail roller 2-1 is realized. When the self-moving tail needs to move left and right or rotate within a small range, the self-moving tail can deflect and move through the travelling mechanism 1-1, and meanwhile, the third telescopic driving device 3-3 is telescopic, so that the steering movement of the self-moving tail is realized, and further the deflection and the small-range rotation of the self-moving tail are realized.
The automatic deviation-adjusting belt conveyor self-moving tail provided by the embodiment, the automatic deviation-adjusting belt conveyor self-moving tail can move continuously, the continuous belt conveyor is connected with the automatic telescopic device at the rear part in a matching mode, the conveying distance of the continuous belt conveyor can be increased under the condition that the belt conveyor is not stopped, the center of the belt conveyor can be automatically adjusted in the process of increasing the conveying distance, the belt conveyor cannot deviate, normal operation is guaranteed, self-moving of the tail can be achieved, self-following and self-correcting are achieved, the structure is simple, repeated transferring is not needed, the phenomenon that the received materials can be better received by the self-moving tail in the left-right moving mode is reduced, and the phenomenon that the received materials scatter is also reduced in a small range to adapt to different working conditions.
